1). The flybarless design characterizes low power loss and great improvements in efficiency.2). Sophisticated 3-Axis gyro flybarless stabilization system automatically adjusts the controls for stable flight .3). Highly developed low voltage drive system provides a green, environmentally friendly and safe power solution.4). Mini size helicopter for indoors, providing 5-6 minutes of flight time after a full charge.5). The RX firmware can Update Online (required UP02 upgrade cable and adapter ).6). Telemetry function can be accomplished after update the RX firmware. The Telemetry helps you get a real time data feedback about the Battery Voltage.(A telemetry function Radio is a must)
